Prior to the 64th Congress, per Article 1, Section 3, Clause 1 of the Constitution, all senators had been "chosen by the [State] Legislature thereof." (As a practical matter, many senators had been "elected"; however, technically, those elections were subject to affirmation by the State Legislatures.)[1]
However, 32 senators of the 64th Congress - those of Senate Class 3 - were directly elected by popular vote in the 1914 United States Senate Elections as directed by the 17th Amendment. The 17th stipulated that it "...shall not be so construed as to affect the election or term of any senator chosen before it becomes valid as part of the Constitution." Thus, Class 1 and 2 senators were not subject to election until 1916 and 1918, respectively. (Note, however, that should a senator have perished prior to the end of his term, then their replacement would have been subject to direct election as they would not have been "chosen before" ratification. This is why Augustus Bacon was the first senator constitutionally elected on July 15, 1913.)[1]
